Answer:

The value of the discriminant = 132

Step-by-step explanation:

4x^2 - 2x - 8 = 0

Using the discriminant

b^2 - 4ac

a = 4

b = -2

c = -8

Using the coefficients with also adding the signs before each

Insert the values

b^2 - 4ac

= (-2)^2 - 4 * 4 * (-8)

= 4 - 4 *4 * -8

= 4 - 16 * -8

= 4 - -128

= 132

The value of the discriminant is 132

The recursive formula for an arithmetic sequence is an = an - 1 + d.
LekaFEV [45]
If an is a5
and
an-1 is a4

then using your recursive formula for an arithmetic sequence
an=an-1 +d
then
a5=a4+d

now, a4 =6 and common difference "d"  is d=-11
hence
a5=6 -11
6-11= -5

Point P is the center of the circle below. What is the exact area
Ber [7]

Answer:

192π unit²

Step-by-step explanation:

Given that :

Radius = 24

Area of circle = πr²

Area = π*24²

Area = 576π in²

The Shaded area is 120°

Entire Circumference = 360°

Hence, shaded area = 120°/ 360° = 1/ 3 of the area

1/3 * 576π in²

= 192π unit²
